PLATE-PRINTING AND EMBOSSING PRESS.

' SPEQIFICATION formingpart of Letters Patent No. 695,864, dated March18, 1902.

Application filed March 15, 1901, Serial No. 51,235. (No model) To allwhom it may concern:

Be it known that I, \VILLIAM FULLARD, a citizen of the United States,residing at Colwyn,in the county of Delaware, State of Pennsylvania,haveiuvented a new and usefulImprovement in Plate-Printing and EmbossingPresses, of which the followingis a specification.

My invention relates to improvements in a to plate-printing andembossing press; and it consists of alocking device for the die-chuckthereof.

It further consists of novel details of construction, all as will behereinafter set forth.

'15 Figures 1 and 2 represent partial side elevation and partialsectional views of a looking device embodying my invention, showing theparts in different positions. Fig. 3 represents [a plan View of thedie-chuck employed.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a portion of the frame of aplate-printing or embossing machine, upon which is suitably mounted thedie chuck or carriage B, the same being adapted to travel on said framein a horizontal line and adapted to receive the impressiou'die 0, havingmeans for securing the same therein, said die-chuck being furtherprovided with a tongue or projection D, having an opening E therein. Anysuitable means may be employed for imparting proper motion to saiddie-chuck. F designates a bolt which is guided in the ways G and H onthe frame A and has a coiled spring J connected therewith and a nut Kfor adjusting the tension of said spring. Secured to the said bolt F isa link L, the lower end of which is pivoted, as at N, to a lever M,which is journaled to the frame A, the opposite end of the lever havingconnected therewith a roller P and a bar or rod Q, which passes througha guide R and is provided with aspringS and an adjusting-nut T. Udesignates a cam suitably journaled on the frame A, to which power isapplied and which has the depressed portion V, it being noticed that thespring S is adapted to hold 50 the roller P in contact with said cam Uat all times, the said spring being stronger than the spring J.

The operation is as follows: The parts being in the position seen inFig. 1 and motion being imparted to the die-chuck B, the same movesforward until it assumes the proper position beneath the plunger W, themotion of the cam U being so timed that when said carriage is in thisposition the roller P will enter the depression V by reason of theaction of the spring S. This carries down one end of the lever andforces up the opposite end and with it the link L and the bolt F, whichthus enters the opening E in the tongue D of the die-chuck, which issecurely locked in position, while the plunger W imparts the impressionto the paper or material A. The cam U continuing to revolve, the rollerP rides up the inclined face and forces down the opposite end of thelever and removes the bolt F, from the opening E, and the carriage movesbackward to receive the next charge of ink.

It will be noticed that by reason of the spring J a quick return isassured to the bolt F, for should the lever M or any of the connectingparts break the spring Jwill immediately remove the bolt from theopening H, p the importance of which is apparent.

It will be evident that various changes may be made by those skilled inthis art which will come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a plate-printing and embossing machine, aplunger, a die-chuck andabolt adapted to enter said chuck when in the proper position beneaththe plunger and lock the same.

2. In a plate-printing and embossing machine, a plunger, a die-chuck, abolt mounted in the frame of the machine as guide and 5 adapted toengage with said chuck to positively lock the same during the period ofembossing, and means for causing said bolt to automatically engage withand disengage from said chuck. I00

'alinement with said plunger which insures perfect registration.

5. In a plate-printing and embossing machine, a plunger, a bed, anopening. therein, a bolt adapted to move in said opening in the bed as aguide and to fit the same closely, a die-chuck, an opening therein whichis adapted to register with the opening in the bed when the die-chuck isin perfect alinement' with the plunger, and means for causing said boltto enter and leave the opening of the chuck, whereby the latter islocked to the bed at the proper time.

6. In a plate-printing and embossing machine, a bolt suitably mount-edin the frame of the machine, a lever, a connection between one end ofsaid lever and said bolt, a cam adapted to contact with the opposite endof said lever in order to raise and lower the same, whereby said bolt isoperated.

7. In a plate-printing andv embossing machine, a bolt, a die-chucksuitably guided, a lever suitably connected to the frame of the machine,a connection common to one end of the lever and said bolt, an armcarried by the other end of said lever, and being suitably pivoted, acam suitably supported adjacent to the end of the lever and a springadapted to hold said lever in contact with said cam.

WVILLIAM FULLARD.
